CROSS-REFERENCE TO RELATED PATENT APPLICATION

This application is related to and claims priority to U.S. Provisional Patent Application Ser. No. 63/257,857, filed Oct. 20, 2021, entitled AUTHENTICATION OF WEARABLE DEVICES ASSOCIATED WITH A PREMISES SECURITY, the entirety of which is incorporated herein by reference.

TECHNICAL FIELD

The present invention relates to premises security systems and/or security systems, and in particular, to wearable devices used in the security system and/or premises security system.

BACKGROUND

Some devices that can be worn on a person's body and include certain electronic components, e.g., used for wireless communication, are typically referred to as wearable devices. Wearable devices are gaining popularity but do not yet reliably identify a wearer and/or determine whether the wearer is an authorized wearer. Although some wearable devices include fingerprint scanners to identify the wearer, including fingerprint scanners add at least complexity, and/or physical size to wearable devices. In other words, typical wearable devices either allow anyone who has possession of the wearable device to use the features offered by the wearable device or the wearable device requires complex fingerprint scanning.

Referring to the drawing figures, in which like elements are referred to by like reference numerals, there is shown in FIG. 1 a diagram of an example system 10 comprising a premises security system 12 and/or at least a wearable device 22. Premises security system 12 comprises a controller unit 14 and/or premises devices 16 a and 16 n (collectively referred to as premises device 16). Controller unit 14 may be configured to communicate with any component of system and perform and/or trigger at least one premises security action associated with any component of system 10. Although premises security system 12 is shown as comprising premises devices 16 a and 16 n, premises security system 12 is not limited to comprising only premises devices 16 a and 16 n and may include additional premises devices 16. Any premises device 16 can be in simultaneous communication and/or configured to separately communicate with more than one other premises device 16 and/or other premises security system 12 and/or other system Although premises device 16 is included in the premises security system 12, premises device 16 is not limited to being included in the premises security system 12 and/or system 10 and may reside standing alone, as part of another system, or in any other manner.

Further, each premises device 16 may include one or more of sensors, control panels, control devices, image capture devices, life safety devices, life style devices and other devices. For example, the types of sensors may include various life safety related sensors, such as motion sensors, fire sensors, carbon monoxide sensors, flooding sensors and contact sensors, among other sensor types. The control devices may include, for example, one or more lifestyle (e.g., home automation) related devices configured to adjust at least one premises setting such as lighting, temperature, energy usage, door lock and power settings, among other settings associated with the premises or devices on the premises. Image capture devices may include digital cameras and/or video cameras, among other image capture devices.

In yet another example, with respect to a door contact detector, monitoring data may include data representing a sensor location and time of detection, among other data related to the door contact detection that may be communicated with remote monitoring center 18.

Alarm event data from the premises devices 16 may be used by the remote monitoring center 18 for performing various safety response processes in notifying the owner of the premises, determining whether an actual alarm event is occurring at the premises, and notifying any appropriate response agency (e.g., police, fire, emergency response, other interested parties such as premises owners, etc.).

Further, system 10 may include wearable device 22 and/or authentication device 26. Wearable device 22 may be a device worn by a user and that is configurable for direct/indirect communication with authentication device 26 and/or any other component of system 10. In a non-limiting example, wearable device 22 may be a device that is not being worn but is within a predetermined proximity to a person associated with the device and/or a predetermined proximity to any of the components of system 10. In another non-limiting example, the wearable device 22 may generally be considered as being removably attachable to a person. Wearable device 22 may include a status unit 24 which may be configured at least to determine to cause a transmission of a signal indicating at least a worn state of the wearable device 22, e.g., where the transmitted signal is configured to cause at least the authentication device 26 to trigger the at least one premises security action. The worn state of the wearable device 22 is not limited to a state indicating whether the wearable device 22 is worn and may indicate any other state. According to various embodiments, non-limiting examples of wearable devices 22 include wireless-enabled electronic watches, sunglasses, rings, bracelets, subdermal implants, etc. that have the ability to communicate with other electronic devices.

FIG. 7 is an example signaling diagram according to the principles of the present invention. Wearable device 22 powers ON, e.g., a user powers ON the wearable device 22 (Step S142). Wearable device 22 transmits an advertisement indicating that wearable device 22 is NOT PAIRED (Step 144). Authentication device 26 adds wearable device 22 as an authorized device of premises security system 12 (Step S146). Authentication device 26 associates a first security token with wearable device 22 (Step S148). The first security token is usable to validate that the wearable device 22 is an authorized device of the premises security system 12. Authentication device 26 transmits the first security token to wearable device 22 for use in future validation of wearable device 22 (Step S150). Wearable device 22 receives and stores the first security token (Step S152). Wearable device 22 advertises that wearable device 22 is PAIRED/NOT WORN such as via advertisement beacons (Step S154).

Wearable device 22 detects wearable device 22 is being worn (Step S156). Wearable device 22 transmits a status update indicating that wearable device 22 is being worn (Step S158). The status update is based on the detection that wearable device 22 is being worn. Authentication device 26 requests the first security token from wearable device 22 via, for example, a secure connection (Step 160). The request for the first security token is in response to the status update of Step S158. Wearable device 22 transmits the first security token to authentication device 26 to validate wearable device 22 (S162).

Authentication device 26 verifies user (Step S164). For example, authentication device 26 may use a pop-up notification on a display of authentication device 26 to ask/request that the user confirm that the user is in control or wearing of wearable device 22. After the user has been verified, authentication device 26 replaces the first security token with the second security token (Step S166). For example, authentication device 26 may update the current security token to the second security token such that the first security token may be discarded. The second security token is usable to validate that the wearable device 22 is an authorized device of the premises security system and usable to trigger a premises security system action. The first security may not be usable to trigger a premises security system action. In one or more embodiments, the first security token is no longer usable to validate that the wearable device 22 is an authorized device of the premises security system.

Authentication device 26 transmits the second security token to wearable device 22 for future validation of the wearable device 22 such as to, for example, trigger a premises security system action (Step S168). Wearable device 22 receives the second security token and replaces the first security token with the second security token (Step S170).

Having described the general process flow of arrangements of the various embodiments and having provided examples of hardware and software arrangements for implementing processes and functions, the sections below provide details and examples of arrangements for authenticating wearable devices 22 used in a premises security system 12 and/or premises security system 12 and/or performing at least one premises security action.

One or more wearable device 22 functions described below may be performed by one or more of processing circuitry 36, processor 38, status unit 24, etc. One or more authentication device 26 functions described below may be performed by one or more of processing circuitry 66, processor 68, authentication unit 74, etc.

In some embodiments, at least wearable device 22 and/or authentication device 26 perform at least one of the following steps: (1) user authorization/verification for using wearable device 22; (2) storing a security token on the wearable device 22 based on the verification; and (3) use of the security token stored at the wearable device 22 to trigger at least one premises security action, e.g., perform a premises security system function.

For user authorization, authentication device 26 (e.g., a computer, phone, or any other device) may prompt the user to confirm that the user is in control of the wearable device 22. However, the user authorization performed on the authentication device 26 is not limited to a prompt and may be any other authorization process such as a face recognition process, a fingerprint recognition process, and/or any other recognition process. In a non-limiting example, a user's face may be recognized by a video capture device, e.g., a camera. The face recognition may be limited to occur within a predetermined time window of wearing (e.g., initially attached or initially wearing) wearable device 22 for user to be authorized. Further, a user may be authorized if wearable device 22 is ‘worn’ while wearable device 22 is within a predetermined area, e.g., an area including at least one component of system 10 such that the user is considered to be on premises. User authorization when the user is considered on premises may trigger automatic trusting of the user of the wearable device 22, thereby authorizing the user and, for example, causing a security token to be stored in wearable device 22.

When more than one wearable device 22 is being used by a user, e.g., wearable device 22 a and wearable device 22 b, obtaining user authorization may require each wearable device 22 to be worn within a predetermined time window. Further, each wearable device 22 having a worn state within a predetermined time window causes the authentication device 26 and/or any other component/device of system 10 to trigger/perform at least one premises security action.

In addition, the security token stored at the wearable device 22 may be used to validate the wearable device 22 and/or cause the authentication device 26 and/or any other component/device of system 10 to trigger/perform at least one premises security action such as a life-safety action and/or a life-style action. A life-style action may include any automation action. In a non-limiting example, at least one premises security action that typically requires a Personal Identification Number (PIN) when requesting to access or when leaving the premises may be triggered/performed when the wearable device 22 is validated, in the worn state, and within a predetermined proximity to the premises, thereby skipping the step of having to manually/physically enter a PIN in a keypad associated with the premises security system 12. Premises security actions that typically require a PIN may include arming/disarming, switching arm states (e.g., away/stay), access control for Multi-Dwelling Unit (MDU) and/or Medium-Sized Businesses (SMB) situations such as locking/unlocking a door where one or more of these actions/functions may be performed using the wearable device 22, as described herein. Further, at least one premises security action (e.g., performed/triggered by authentication device 26 and/or any other component/device of system 10) includes a life-style action such as changing light brightness and/or turning a fan on. The life-style action may be associated with a particular user and/or wearable device 22.

Some other embodiments provide a process for detecting an authorized user of a wearable device 22. The wearable device 22 may be configured to determine when the wearable device 22 is being worn, and advertising, e.g., by transmitting a signal, that a state, e.g., a worn state, has changed. The wearable device 22 may then wait for an authentication device 26, e.g., such as a mobile device, to wirelessly connect to the wearable device 22. When the authentication device, e.g., the mobile device, connects and verifies that wearable device 22 is a valid device, the authentication device 26 may then generate a prompt, e.g., for a user of the wearable device 22 and/or the authentication device 26, to verify/confirm that the user is the person who has physical control of the wearable device 22, e.g., the user has just put on the wearable device 22. Upon receiving confirmation from the user, authentication device 26, e.g., the mobile phone, and/or software 72 and/or a software application 76 of the authentication device 26 instructs wearable device 22 to change behavior such that wearable device 22 advertises, e.g., by transmitting at least a signal including packets, that wearable device 22 is now being worn. A flag may be set and/or a byte/bit may be changed when the wearable device 22 is worn (i.e., determined/detected to be worn) and validated (e.g., by the authentication device 26). One of the benefits of setting the flag and/or changing the byte/bit is avoiding querying (e.g., constant querying) of some wearable devices 22 (e.g., wearable devices 22 that have not been worn/validated) to obtain a wearable device state. Put differently, setting the flag and/or changing the byte/bit allows querying (e.g., limiting querying to) the wearable devices 22 for which the flag has been set and/or the byte/bit changed such as wearable devices 22 that have been worn/validated.

When wearable device 22 detects that is no longer being worn, wearable device 22 may change its advertising, e.g., by transmitting at least another signal including packets, again to reflect another worn state, i.e., not being worn. At this point, authentication device 26, e.g., a mobile phone, and/or controller unit 14 and/or remote monitoring center 18 and/or a premises device 16, e.g., a security base, a keypad, can connect such as via a receiver/transmitter to wearable device 22, validate a security token associated with the wearable device 22, and/or take/trigger at least one premises security action, as described herein. For example, the wearable device 22 may trigger the premises security system 12 arm based on the location of the wearable device 22, or may trigger lights in a particular room to turn on when the wearable device 22 is detected by the premises security system 12 as being located in that room, etc.

Wearable device 22 may detect, e.g., via status unit 24, that is being worn or not worn. In some embodiments, wearable device 22 may detect, e.g., via status unit 24, that is being worn and not worn by using, e.g., as part of and/or in communication with status unit 24, any one of the following:

-   -   A reed switch on at least a part of a strap (e.g., attachment         mechanism/device/entity) of wearable device 22, e.g., on half of         a strap, with a magnet on the remaining part of the strap. The         strap may include but is not limited to a watch strap, a         necklace clasp, and bracelet clasp;     -   A hall effect sensor on a part of a strap of wearable device 22,         e.g., on half of a strap, with a magnet on the remaining part of         the strap. The strap may include but is not limited to a watch         strap, a necklace clasp, and bracelet clasp;     -   A spring clip with conductors that close a circuit associated         with wearable device 22 when wearable device 22 is unclipped,         e.g., from clip-on earrings, or lapel clip.     -   Conductors on each end of a strap that make an electrical         connection when the strap is closed, e.g., on a watch strap or         bracelet strap;     -   A capacitive sensor on wearable device 22, where the capacity         sensor measures proximity to a person. The capacity sensor may         be included as part of a wearable device that is, for example, a         watch, bracelet, or ring;     -   A heat/pulse sensor measuring proximity to a person. For         example, the heat/pulse sensor may be included in a wearable         device 22 that is, for example, a watch, a bracelet, or a ring;         and     -   Although other attachment mechanisms/devices may be used where         the worn state of the wearable device is able to be determined         based on, for example, a characteristic of the attachment         mechanism/device and/or characteristic of the wearable device         with respect to the user, etc.

Further, wearable device 22 may be configured to advertise its state (e.g., worn state) and/or establish and/or maintain wireless communication, e.g., secured wireless communication, to any other component/device of system 10, e.g., a software application 76 on authentication device 26 such as a mobile phone, a premises device 16 such as system receiver. In a non-limiting example, wearable device 22 may be configured to establish and/or maintain wireless communication by using BLUETOOTH (BLE), WiFi, or any other RF protocol.

In some embodiments, when BLE is used, the following steps may be performed. Wearable device 22 is powered on and begins transmitting periodic BLE advertising beacons, e.g., signals, indicating that it is “not paired.” Using software application 76, e.g., a mobile application on a mobile phone, a user adds wearable device 22 to system 10, e.g., using a secure BLE connection. Software application 76, e.g., the mobile application on the mobile phone, securely stores a first security token on wearable device 22. The first security token may be later retrieved for validation, as described herein. Wearable device 22, e.g., after receiving the first security token, may alter its advertising data, e.g., by transmitting a signal, to indicate that wearable device 22 is paired and “not worn.” Wearable device 22 may, e.g., at a later time, detect that the wearable device 22 has been put on, e.g., by using the detection methods described above, and communicate with software application 76, e.g., the mobile application on the mobile phone, to indicate a change in the worn status of the wearable device 22.

Software application 76 may securely connect to wearable device 22, retrieves the first security token used for validation, e.g., to confirm that wearable device 22 is a valid device, i.e., that wearable device 22 is the wireless device previously paired. Software application 76 may generate a notification, e.g., such as a pop-up notification on the display of the mobile phone, prompting the user to confirm that the user is in control of wearable device 22. In order to confirm, the user of the wearable device 22 may use multiple methods, including but not limited to unlocking, authentication device (e.g., the mobile phone) and/or press a button display by software application 76. After receiving confirmation, software application 76, e.g., the mobile application, authorizes wearable device 22 and/or stores a second security token, e.g., a new security token, on wearable device 22 for further validation. Then, wearable device 22 begins sending advertising beacons, e.g., transmitting at least a signal, indicating that wearable device 22 is in the “worn” state. It is noted that the steps performed by software application 76 may be performed by any other component/device of system 10 and/or authentication device 26 may be part of any other component/device of system 10, e.g., part of controller unit 14 and/or premises security system 12 and/or remote monitoring center 18.

In some other embodiments, a wearer/user of the wearable device 22 may activate wearable device 22, e.g., via a panic button. For example, the user may activate wearable device 22, thereby altering advertising packets transmitted by the wearable device 22, e.g., to indicate or trigger an action such as by pressing a panic button in order to cause premises security system 12 to perform one or more actions. Any other component/device of system 10, e.g., authentication device 26, may receive the advertising packets and/or verify that wearable device 22 is still in the “worn” state and/or connect to wearable device 22 to validate a security token, e.g., the second security token. If the security token is valid, any component/device of system 10, e.g., authentication device 26, software application 76, premises security system 12 performs the action, e.g., system panic.

FIG. 8 is a signaling diagram of an example process for triggering a premises security system according to the principles of the present invention. Wearable device 22 determines to trigger a premises security system action (Step S172). For example, a user may push/activate a panic button and/or provide a verbal and/or touch based input to wearable device 22 indicating the user wants to trigger a predefined premises security system action. Wearable device 22 advertises an indication of the premises security system action and an indication that wearable device 22 is being worn (Step S174). For example, the advertisements may be provided by advertising beacons transmitted by wearable device 22. Authentication device 26 verifies wearable device 22 is being worn (Step 176). For example, authentication device 26 may determine whether a predefined number of additional advertisement beacons have been received after receiving the first advertisement beacon.

Authentication device 26 transmits a request for the second security token (Step S178). For example, the request may be in response to the advertisement of Step S174 and verification in Step S176. The wearable device 22 receives the request and transmits the second security token to authentication device 26 such as via a secure connection (Step S180). Authentication device 26 validates the second security token (Step S182) and triggers the indicated premises security system action based on the validation (Step S184).

When a wearer removes device and/or causes the wearable device 22 to indicate that the wearable device 22 is not worn, or a ‘worn’ detection has failed, wearable device 22 may alter beacon data to indicate that wearable device 22 has been removed and/or is not worn.

Any other component/device of system 10, e.g., authentication device 26, may then receive beacon, connects to wearable device 22, validates the security token, perform an action, e.g., panic, in response to the change of worn state change, and/or note that wearable device 22 is no longer being worn by an authorized user.

FIG. 9 is signaling diagram of an example process performed when the wearable device 22 is removed, according to the principles of the present invention. Wearable device 22 detects wearable device 22 is not being worn (Step S186). For example, hardware such as sensors and/or mechanisms may indicate that worn detection has failed (i.e., wearable device 22 is not being worn). Wearable device 22 advertises that wearable device 22 is NOT WORN/PAIRED (Step S188). For example, wearable device 22 indicates, via advertisement beacon(s), that wearable device 22 is paired with authentication device 26 and not being worn. Authentication device 26 requests a second security token from wearable device 22 in response to the advertisement of Step S188 (Step S190). The second security token is usable to validate that the wearable device 22 is an authorized device of the premises security system 12. Authentication device 26 receives the second security token and validates the second security token (Step S194). Authentication device 26 determines wearable device 22 is not worn by an authorized user such as based on the determination of Step S194 (Step S196). Authentication device 26 triggers a premises security action and/or updates the status of wearable device 22 stored in its memory to indicate wearable device 22 is no longer being worn by the authorized user (Step S198).

Worn state changes may happen either in range or out of range of any component/device of system 10. The component/device, e.g., authentication device, may re-validate wearable device 22 once the component/device begins receiving advertising packets again. For example, it may not make sense for a panic event that occurred out of range of the component/device to be reported after a certain amount of time has elapsed.

Broadcasting a worn state, such as a worn state change (e.g., going from worn to not worn when the wearable device 22 is removed or detached) allows at least one component/device of system 10, e.g., authentication device 26, to passively receive at least one advertising packet and discard it without taking further action. Otherwise, every time an advertising packet is received, additional steps may be required such as reaching out to wearable device 22 and requesting a stored security token to determine whether the wearable device 22 is still secured. Performing the additional steps may become a resource intensive operation, e.g., for a battery of wearable device 22.
